RAILWAY-GATE.

SPECIFICATION forming part of Letters Patent No. 625,740, dated May 30,1899. Application filed December 30, 1898. Serial'No. 700,685. (Nomodel.)

To all whont it may concern.-

Be it known that we, LYMAN CARRIER and E810 Z. GLOW, citizens of theUnited States of America, residing at Joliet, in the county of Will andState of Illinois, have invented certain new and useful Improvements inRailway-Gates, of which the following is a specification, referencebeing had therein to the accompanying drawings.

This invention relates to certain improvements inrailway-gates for usein closing a street and sidewalk to travel while a railwaytrain iscrossing them, and relates more particularly to the class of gateswherein a gatearm is used to be elevated and lowered across the streetand sidewalk, which improvements are fully set forth andexplained in thefollowing specification and claim, reference being had to theaccompanying drawings, and the letters and figures of reference thereon,in which- Figure 1 is a prspective view'of the gates as they wouldappearlet down across the roadway and sidewalk to close them to travel.Fig. 2 is a plan View of a short section of a link belt, having asection of a cable attached thereto; and Fig. 3 is a side View of theupper end of one of the posts and of the inner ends of a gate-bar andsidewalk-gate bar pivotally connected to said post and with each otherand of a link belt for operating said gates, the broken lines showingthe position of said gate-bars as they would appear raised to open theroadway and sidewalk to travel.

Referring to the drawings, A represents the four gate-arms, having theirinner ends .pivotally connected to the posts D neartheir upper ends bymeans of a short shaft S, having a sprocket-wheel O secured on its outerend, and provided near their outer ends with depending rod-supports Jfor maintaining them in a horizontal position when let down. B aresidewalk-gate arms having their inner ends pivotally connected to saidposts near their upper end adjacent to the inner ends of the gate-arms Aand connected therewith through the medium of segmentgearsarranged,respectively, one on each inner end of said gate-arms A and B and inmesh with each other, as shown more particularly in Fig. 3, so that whenthe gate-arms A are elevated and lowered they will simultaneouslyelevate and lower the sidewalk-gate arms B, as shown in broken lines inFig. 3. F is a steel-wire cable for operating said gatearms by engagingthe sprocket-wheels O of the gate-arms A, said cable having sections ofa link belt L inserted where it engages said sprocket-wheels. Said cableis one continuous length and engages and operates all four of thegate-arms simultaneously. The two ends of the cable attach to the leverE, one at either side of its fulcrum G, so that movement of said leverin either direction will turn the gate-arn1s either up or down.

Fig. 1 shows a pair of gate-arms placed one at either side oftherailroad-track R and connected by the cable F, which is arranged topass underneath said track, as shown in the broken lines. Said cable Fhas one end attached to the lower end of leverE and passes from thenceunder pulleys 2 and 5, around pulley 7, under pulley 12, up oversprocketwheel 0, under pulleys 11 and 8, up over pul- Iey 10, and incontact with sprocket-wheel C, under pulleys 9 and 6, up oversprocketwheel 0 under pulleys 4 and 3, up over pul ley 13, and incontact with sprocket-wheel C under pulley 1 to lever E, to which it isattached between its fulcrum and outer end, by means of whicharrangement and connection with the gate-arms they may all besimultaneously turned eithernp or down by operating said lever forwardand backward. The reverse position of said lever F. from that shown inFig. 1 would raise all the gate-arms up, as shown in broken lines inFig. 3.

The cable F, it will be observed, is ar ranged to pass under the roadwayand railway, so as to be out of'the wayand be protected from injury orinterference of anything passing along the roadway or railway, as isshown. in Fig. l, the broken lines showing howthe cable passes under therailway, so as to connect the gate-bars at either side of the railway,the whole forming a very effective and durable system of gate-bars forsuch purpose.

Having thus described our invention, what we claim as new, and desire tosecure by Let ters Patent, is as follows, to wit:
